|Tools for this tag|
This tag is used to identify historic features which are in ruins.
For ruined structures that have no historic importance it can also be used in conjunction with other tags, such as 'building'. For example: building=yes, ruins=yes, but it's better to use building=ruins and abandoned:building=yes in this case.

As ever in OpenStreetMap, you are free to tag as you like, but you can read further here to make your own opinion : here or there.
In some cases the value of the "ruins" tag has been used to provide additional information in the form ruins=tower. See discussion page for proposals to extend this option.
There is a proposed icon for generic ruins:
